can anyone explain me that i dont get it 
i have 22 in my Inventory but at Upgrade it says 0
You have the greater leapstones in your inventory, not the smaller ones 
hmm ok then it tells me wrong so what can i do with the big ones now? looks like they are useless for Upgrade @Kakaochen
They are used at higher item level, 1370 I think. You will use them later. But you can also sell them for gold if they are unbound and buy the ones you need ^^
oh ok thx
